Just like in “300”, Spartan boys were sent off to start training for the military at the age of 5. They lived in barracks to learn about brotherhood and weaponry. By the age of 12 they were taught to survive in the wild, often with nothing more than their weapons and a cape- no shoes. When they reached the age of 18, life was essentially all about the military. Spartan warriors were brought up to understand that their entire lives were dedicated to the state of Sparta. This allowed them to be so powerful. A man was expected to be able to serve the Spartan Military until the age of 60.
